The study was carried out during the 2018-2019 growing season under greenhouse conditions to determine the population development and infestation rates of Thrips, Leafhopper species, and Tuta absoluta damaging greenhouse tomatoes in Karatay and Meram (Konya) districts. For this purpose, 10 greenhouses of tomato were selected from the two districts. Delta-type sexual pheromone trap, blue and yellow sticky traps were hung in each greenhouse. The traps were placed in the greenhouses alongside tomato seedlings. The pests caught in these traps were counted weekly and recorded. The infestation rate of 25 plants was selected randomly from each greenhouse and their pest infestation was examined. As a result of this study, Thrips species in the districts were found in the early stage of the plant in blue traps and were recorded to be 29 and 7 pests per week in Karatay and Meram respectively. Leaf hooppers species emerged in yellow sticky traps during the last stages of plant phenology; and in 2018-2019, a maximum of 5-4 pests per week was determined, respectively. Tuta absoluta, on the other hand, had a high population at the end of the season; in 2018-2019, a maximum of 636-571 adult pests per week were caught on the traps, respectively. In 2018-2019, whereas the infestation rate of Thrips and Leafhopper species were 0%, the infestation rate of T. absoluta was 18.66% and 18.76%, respectively
